Setting Analog I/O Terminal (TBAIO)
The controller has two analog I/O terminals that can be set to voltage mode or current mode. It can output voltage/current through an external device operated using analog I/O or receive signals from sensors outputting analog voltage/current.
To ensure maximum input accuracy, observe the following:
- Use shielded or twisted pair cables.
- Connect the cable shield to the ground terminal inside the controller.
- Current signals are relatively less sensitive to interference, so use devices operating in current mode for analog I/O terminals. Current/voltage input modes can be set with the software.
The electrical specifications of the analog I/O terminal are as follows:
Terminal | Parameter | Specification | |
|---|---|---|---|
Current mode analog input | [AIx-GND] | Voltage | - |
[AIx-GND] | Current | 4 - 20 mA | |
[AIx-GND] | Resistance |

[AIx-GND] | Resolution | 12 bit | |
Voltage mode analog input | [AIx-GND] | Voltage | 0 - 10 V |
[AIx-GND] | Current | - | |
[AIx-GND] | Resistance | 1M ohm | |
[AIx-GND] | Resolution | 12 bit | |
Current mode analog output | [AOx-GND] | Voltage | - |
[AOx-GND] | Current | 4 - 20 mA | |
[AOx-GND] | Resistance | 50M ohm | |

Voltage/current input
It receives voltage or current signals from an external device between the Alx terminal of the TBAIO terminal block and the GND terminal. If the output of the device is a voltage signal, it receives a signal of 0-10Vdc. If the output of the device is a current signal, it receives a signal of 4-20mA.
- Depending on the output signal (voltage/current) of the device, it is necessary to set the controller analog input as “Voltage” or “Current” on the teach pendant.
Voltage/current output
It supplies voltage or current signals to an external device between the AOx terminal of TBAIO terminal block and GND terminal. If the input of the device is voltage signal, it supplies a signal of 0-10Vdc. If the input of the device is current signal, it supplies a signal of 4-20mA.
- Depending on the input signal (voltage/current) of the device, it is necessary to set the controller analog output as “Voltage” or “Current” on the teach pendant.
